st: graph combine question

Dear listers,
I'm making a 2 col by 3 row ROC graph utilizing -graph combine-. I'm
labeling every y-axis in column 1 with sensitivity vertically and
every x-axis in row 3 with 1-specificity horizontally. However I'd
also like to add a horizontal title for each row and the graph editor
only allows 2 (as far as I can see). I'm using the top1 and top2
positional title option to label each column. Any ideas?
Regards,
M
